## Isothermal ???

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### Isothermal ???

When temperature is constant but volume changes, why is the change in internal energy equal to 0?

It might have to do with the fact that although work is being done and energy is being used, the same energy is put back into the system in order to keep the system at a constant temperature. Hope this helps.
